+	A comma-separated list of option enables fuzzy collection for specific
+	|ins-completion| modes, affecting how items are gathered during
+	completion. When set, fuzzy matching is used to find completion
+	candidates instead of the standard prefix-based matching. This option
+	can contain the following values are:
+
+	keyword		keywords in the current file |i_CTRL-X_CTRL-N|
+			keywords with the ".", "w", "b", "u", "U" and
+			"k{dict}" flags in 'complete'. |i_CTRL-N| |i_CTRL-P|
+
+	files		file names  |i_CTRL-X_CTRL-F|
+
+	whole_line	whole lines |i_CTRL-X_CTRL-L|
+
+	When used with 'completeopt' "longest" option, fuzzy collection can
+	identify the longest common string among the best fuzzy matches and
+	automatically insert it.
